The first two generation squarks are quasi-degenerate. The
minimal level of degeneracy is \((\tilde{m}_2-\tilde{m}_1)/(\tilde{m}_2+\tilde{m}_1)\lesssim 0.1\) . It could be the result of RGE
[1]}. However, for maximal phases, the bound is even
stronger, of order 0.04 [2]}, which is difficult to
achieve with just RGE effects.

The first two generation squarks are heavy. Putting
\(\sin \theta _u=0.23\)  and \(\sin \theta _d\approx 0\) , as in models of
alignment [3]}, [4]}, lowlnp2 leads
to
\(m_{\tilde{q}}\gtrsim 3.\) 

The ratio \(x=\tilde{m}_g^2/\tilde{m}_q^2\)  is in a fine-tuned
region of parameter space where there are accidental
cancellations in \(11\tilde{f}_6(x)+4xf_6(x)\) . For example, for
\(x=2.33\) , this combination is \(\sim 0.003\)  and the bound
(REF ) is relaxed by a factor of 7.
